Cut the pork shoulder into 4" chunks and place inside the instant pot.
Add the orange juice, lime juice, salt, cumin, chili powder, garlic powder, onion powder, oregano, black pepper and broth to the instant pot. Mix thoroughly to coat the pork.
Place the lid on the Instant Pot, making sure the valve is in the "sealed" position. Pressure cook on high for 45 minutes.
Let the pressure naturally release for 15 minutes before quick releasing the rest.
Remove the lid and shred the pork with two forks. It's now ready to add to tacos, burritos, or more!
